Are all molecules of ideal gas in motion with different velocities?
Explanation:
Individual gas molecules have different speeds. Collisions between these molecules can change individual molecular speeds, but this does not affect the overall average speed of the system.
Lithium seems to have dramatic effects on the nervous system, yet our bodies seemingly never evolved to use lithium endogenously, rather focusing on sodium, potassium, and calcium. what is a plausible explanation for this?
Given its small size and high polarizing power, lithium is only involved in covalent rather than ionic bonds in the body as does sodium, potassium, and calcium.
What is lithium?Lithium is a metal and a member of group 1 in the periodic table. It is a very small ion hence it has a different chemistry from the rest of the members of the group.

Explanation:
The antibiotic prontosil, developed by bayer pharmaceuticals in 1932, was used in saving the life of president roosevelt's son from severe strep throat in 1936. protonsil consists of two nitrogens bonded together in a double bond. the left nitrogen is bonded to a benzene ring where the para position contains a sulfur double bonded to two oxygen atoms and single bonded to n h 2. the right nitrogen is bonded to a benzene ring where one ortho and the para position each have an n h 2 substituent. substituent prontosil is an azo dye, which can be prepared from an aryldiazonium ion and an aromatic compound. draw the structures of the diazonium ion and the coupling component for this drug

What is Molar mass?A chemical compound's molar mass is calculated by dividing its mass by the number of moles—measured in moles—that make up the sample of that compound. A substance's overall characteristics include its molar mass. The compound is present in many different forms, each with a different mass as a result of the isotopes. The molar mass is the average of these masses. The molar mass is most frequently calculated using the standard atomic weights and is a function of the relative abundance of the constituent atoms' isotopes on Earth. It is thus a terrestrial average. For converting between a substance's mass and its amount for large quantities, use the molar mass.To learn more about Molar mass, refer to:

Explanation:
Calcite (the main mineral in limestone) is made of calcium carbonate (caco3). dolomite, a related mineral, is made of magnesium carbonate (mgco3). what happens if a geologist drips a small amount of vinegar (acetic acid) onto a sample of dolomite? there is no way to predict what will happen. fizzing will occur because carbon dioxide is produced. no reaction will occur because dolomite contains no calcium.
If a geologist drips a small amount of vinegar (acetic acid) onto a sample of dolomite, fizzing will occur because carbon dioxide is produced.
Why Carbon dioxide show effervescence?Effervescence observes whenever any gas tried to escape out from an aqueous solution, that's why CO₂ show effervescence.
Reaction between dolomite and acetic acid will be represented as:
MgCO₃ + 2CH₃COOH → CO₂ + H₂O + Mg(CH₃COO)₂
From the above reaction it is clear that carbon dixide gas is produced by showing the effervescence and fizzing behavior.

the compound that has the largest ions with the least charge
the compound that has the smallest ions with the greatest charge
the compound that has the smallest ions with the least charge
Answer:
the compound that has the smallest ions with the greatest charge
The compound that has the smallest ions with the greatest charge will have the strongest ionic bonds. Therefore, option C is correct.
What are ionic compounds?Ionic compounds can be defined as solids formed by closely packed ions of opposite charge. An Ionic compound is commonly formed when metal combines with non-metal.
In ionic compounds, the ions are held together by ionic bonds. The ions are created by accepting or losing electrons in order to get their nearest noble gas configuration. In a reaction, the metals have a tendency to lose electrons to complete their octet while non-metals will gain electrons to fill their octet.
An ionic bond or electrovalent bond is a type of linkage generated from the electrostatic attraction between oppositely charged ions. Such a bond produces when the valence electrons of one atom are transferred permanently to another.
The more the charge on the ions and the smaller the ions stronger the ionic bond will be formed.
